Question “Use data from Appendix IIB in the textbook to calculate ΔS∘rxn for each of the following reactions. C2H4(g)+H2(g)→C2H6…”
Use data from Appendix IIB in the textbook to calculate
ΔS∘rxn for each of the following reactions.
C2H4(g)+H2(g)→C2H6(g)
MgCO3(s)→MgO(s)+CO2(g)
CO(g)+H2O(g)→H2(g)+CO2(g)
2H2S(g)+3O2(g)→2H2O(l)+2SO2(g)
Answer
ASna calculates the entropychange at 298 K. Zms’ (products)-S s’ (reactants) Here,m,n arethe coeffi cients of reactantsandproducts. Below is the given reaction: (g). > CH (g), now, substitute AS0 229.2J/molK+130.7J/molK) 0.8 J/molKASdeg
Below is the given reaction: MgCo3(s)>MgO (s), +CO2 (g, now substitute Aso of Mgo()+So of Co2 (3))-(sdeg MgCO,(s)) AS(27.0J/molK + 213.8J/molK)–(65.7J/molK/ASdeg-175.1 J/molK
Below is the result: substitute ASoa (so of H2 and) + Soof Co, (g ))-(Sof CO(g)+ H,O()) AS 130.7J/molK 2133.8J/molK)-(197.7J/molK +188.8J/molK) ASdeg
Below is the givenreaction: 2HS (g) +302(g) 2H2(1)+2SO2(g). Now, substitute ASI (2×70 J/molK +2×24 8.2J/molK +3×205.8J/molK +3×205.2 J/molK) AS0.8 J/molK
Conclusion
Above is the solution for “Use data from Appendix IIB in the textbook to calculate ΔS∘rxn for each of the following reactions. C2H4(g)+H2(g)→C2H6…“. We hope that you find a good answer and gain the knowledge about this topic of science.
